What ICD-10 codes are used for pneumothorax?

Pneumothorax, a condition characterized by collapsed lungs, is a severe medical situation that needs immediate attention. It is described under several Pneumothorax ICD codes, including:

  • J93.9 - Pneumothorax, unspecified: Used when the medical documentation does not provide sufficient information to specify the type of pneumothorax.
  • J93.0 - Spontaneous tension pneumothorax: Used when the pneumothorax occurs spontaneously and increases pressure in the pleural space. This represents a life-threatening emergency requiring immediate intervention.
  • J93.11 - Primary spontaneous pneumothorax: Used when the spontaneous pneumothorax occurs without any underlying lung disease.
  • J93.12 - Secondary spontaneous pneumothorax: Utilized when spontaneous pneumothorax occurs due to an existing lung disease such as cystic fibrosis, chronic obstructive pulmonary disease, or other conditions classified under respiratory system disorders.
  • J93.81 - Chronic pneumothorax: This code describes a pneumothorax that lasts for a long time or keeps coming back.
  • S27.0XXA - Traumatic pneumothorax, initial encounter: Used for pneumothorax resulting from trauma during the initial encounter for treatment.
  • J95.811 - Postprocedural pneumothorax: Used when pneumothorax occurs as a complication following a medical procedure.
  • J95.812 - Postprocedural air leak: Used for air leak complications following procedures on the respiratory system.
  • P25.1 - Perinatal pneumothorax: Specific code for pneumothorax occurring in newborns during the perinatal period.
  • J94.8 - Other specified pleural conditions: May include asbestos pleural plaque and other pleural cavity disorders that can predispose to pneumothorax.

Which pneumothorax ICD codes are billable?

All of the previously listed ICD codes are billable.

Clinical information

Pneumothorax is a condition where air collects in the pleural space, causing a portion of the lung to collapse. This pathological process can occur due to injury, underlying lung disease, or spontaneously without an apparent cause.

The symptoms include sudden chest pain and shortness of breath. In spontaneous tension pneumothorax, patients may develop severe respiratory distress and cardiovascular compromise.

Treatment often involves removing the air from the pleural space to allow the lung to re-expand. This may include:

  • Needle decompression for spontaneous tension pneumothorax
  • Chest tube insertion for larger pneumothorax
  • Surgery may be required in severe cases or recurrent pneumothorax
  • Management of air leak and pneumothorax and air leak complications

Synonyms include

  • Collapsed lung
  • Lung collapse
  • Air in pleural space
  • Pleural air
  • Pleural cavity air
  • Air leak syndrome
  • Pneumothorax and air leak
